finally got the TIII about half tuned, and im spinning my clutch like a ballerina on speed... anybody know of any good options? what are all you other turbo 20b guys using?

i have been looking at a tilton 7 1/4 triple disk setup- seems to be about the cheapest option, but im having trouble finding prices for all the different parts. anyone know if there is a reasonably priced flywheel for this setup? or if there is some way i might just be able to modify my ACT flywheel to accept one?
or is there some other setup i should check out?

anyone got a used clutch they want rid of?

Since I've been looking into the same thing, I came across this thread. It has some good info from people who have personally used different clutches and can accurately compare them

Basically, the Tilton comes out on top with their carbon/carbon, but also with a price tag.

so the stock input shaft (TII and FD) is 1" x 23 spline.

tilton offers this spline in either a 30 or 45 degree tooth angle. anyone know which one we've got?

also, this is the same shaft/spline used by some ford trannies (which from what I hear are actually mazda products anyway). does anyone know if the ford ones will interchange with ours?

my basic plan on this is:
buy a used tilton twin 7.25 on ebay, they go for rediculously cheap.
buy a set of the proper plates for our tranny (rally disks for s/s use)
either turn/drill my act flywheel, or send it off and have someone else do it (one place says $120, not too bad). to accept the 7.25 clutch

am i missing something or does this sound like reasonable plan?

another good thing about this setup would be that after i kill my current TII tranny and my JDM spare, I will only need a new set of disks to make the clutch work with a T56...

I have no direct experience with the 7.25 clutches but the pressure plate and floaters in the 5 inch clutch tend to warp very quickly, I switched to AP and would say that the floater life nearly doubled. just something to keep in mind for your budget

Pat, Tilton can make a clutch in ANY spline you need. My advice, call up Taylor Race Engineering in Texas (http://www.taylor-race.com/), talk with Scott Young (ONLY him), tell him Ramy sent you, and he'll give you all your optoins.

PS: I may have a used (but excellent condition) HKS GD Max Twin Plate for sale in a few days...

Ive been looking at taylor's site, but i dont think ive got the cash for a totally new setup. I am still kinda hoping that i can pick up a used assembly and just swap in the proper disks.

On the same note, i doubt i can afford your hks, but let me know when you have it and how much you want, and we'll see

I'm planning on buying a Carbonetic twinplate clutch for my project. Competitive retail is about $1,920. If anyone else is interested in getting one let me know -we can probably get a price break
http://www.carbonetic.net/

Based on my correspondence with Carbonetic and Exedy, the Carbonetic clutch appears to be a couple pounds lighter and rated to a higher torque level. In addition, the pressure plate can be upgraded to a stiffer (or softer) setup for under $150 through Carbonetic.

exedy D core (twin plate carbon) works great on my single turbo 20B.

It looks like a nice clutch, but the torque rating was a little low for my unrealistic expectations This is from Kevin Fujioka at Exedy:
"Torque rating: 465Lbs-ft@Wheel (510Lbs-ft@crank if 10% loss by drivetrain)."

For the record, here is the weight he quoted: "Total weight with Flywheel:　27.9Lbs" In a follow up email I asked him if that includes the counterweight and (from memory) I believe he said it does not.

Do they make a triple plate D-core?

ha. finally unbanned so i can post with my real name again.

anyway, I talked to scott at taylor race engineering, who was extremely helpful, and he recommended me the tilton twin rally clutch, rated for 8xx ft-lbs i believe, and total price was around 700 (not including modifying the flywheel and TOB, which i figure i could have done for close to nothing, but they do offer to modify flywheels to accept the 7.25 clutches for $120). unfortunately, i broke some stuff, and cant afford it right now, so that will have to wait until spring.

for right now, i called up xtd, yes, the cheapo ebay company whos 6 puck i have now, and was really surprised to find out how many options they had. the guy is sending me a double heat treated diaphragm pressure plate for $230 shipped, which is supposedly rated at 7xx ft-lbs. the one i have now was supposed to be good for 408, and that seems to be quite accurate, so i think this should hold me for a while. makes me glad that all the cheap ebay companies arent worthless.

I wouldn't do that...

based on what? The 'stage 3' clutch i got from them has performed exactly as advertised for several thousand miles, and I abuse the **** out of clutches. So why should I not believe that the pressure plate will do equally as well? Im sure it will be a pain in the *** to drive with 300% stock clamping force, but I can live with that if it holds, which I think it will. I still plan on getting the tilton, but until I can afford it I need something cheap that will hold the power, and this seems like the perfect answer to me. I'm supposed to get it in the next couple days, I'll post up how it does once its broken in.

I'm a firm believer in 1) you get what you pay for, and 2) most brand name R&D is something you can rely on, worry-free...
